A few dozen people who comprised Lee’s intimate circle gathered on Saturday at a church in the small Alabama town of Monroeville, which the author used as a model for the imaginary town of Maycomb, the setting of her Pulitzer Prize-winning novel To Kill a Mockingbird. Lee died on Friday at age 89.

A longtime friend, history professor Wayne Flynt, eulogized her in a ceremony at First United Methodist Church. Afterwards, her casket was taken by silver hearse to an adjacent cemetery where her parents, AC Lee and Frances Finch Lee, and sister, Alice Lee, are buried. A spray of red and white roses covered the family headstone.

Flynt said he delivered a eulogy that Lee specifically requested years ago. Entitled Atticus Inside Ourselves, it was a tribute Flynt gave in 2006 when she won the Birmingham Pledge Foundation Award for racial justice. Flynt said Lee liked the speech so much that she wanted him to give it as her eulogy.

“I want you to say exactly that,” Flynt quoted Lee as saying at the time. “Not one thing more, and not one thing less.”

“If I deviated one degree, I would hear this great booming voice from heaven, and it wouldn’t be God,” Flynt said in an earlier interview.

Details of the service were fiercely guarded. The author, who for decades declined media interviews, wanted a quick and quiet funeral without pomp or fanfare, family members said.

“We obeyed her wishes,” said Jackie Stovall, Lee’s second cousin.

The town was appropriately somber a day after their native daughter’s death. Black bows adorned the doors of the old courthouse in Monroeville where Lee as a child, like her literary creation Scout Finch, would peer down from the balcony as her lawyer father tried his cases in the courtroom.

Mockingbirds chirped and frolicked among blooming camellia bushes outside the courthouse on a warm Alabama morning that teased the early arrival of spring.

Jared Anton, of Hollywood, Florida, sat outside the old courthouse during part of a planned vacation through the south that coincided with Lee’s death.

Anton said reading the book – in which attorney Atticus Finch defends a wrongly accused African American man – was one of the reasons he decided to become a lawyer.

“It had an impact on me when I was younger. I wanted to do the right thing, to stand up to people, to defend the innocent, if you will,” Anton said. “It is the greatest American novel. Name one that really has had more of an impact on Americans than that book.”

The southern town was home to childhood friends Truman Capote and Lee, giving rise to its self-given nickname of the literary capital of the south. Ann Mote, owner of the Ol’ Curiosities & Book Shoppe in Monroeville, said she thinks the town will always be linked to Lee.

“She’s a part of it and always will be,” Mote said.

The town this summer had a celebration for the release of Go Set a Watchman – Lee’s initial draft of the story that would become To Kill a Mockingbird – even though many residents had ambivalent feelings about its release.

“She was an Alabama treasure. She was an international treasure. We were all blessed by her life and her work as we are diminished by her passing,” said Cathy Randall, a friend of Lee’s for the past 30 years.

Flynt and Randall said they had recently visited Lee at the Monroeville assisted living facility where she had lived for several years because of declining health. Flynt said Lee was “savagely witty”.
